it again and see, reason I know there are files on it is the boot up logo is working and it
is found on a working maxisys by clicking root explorer navigate to system, media
there is a file called bootanimation.zip which is the boot animation and that is in the
root of the device, so please connect again and based on what you see I might be able
to help.
